Power Supply
The mains connection is on the rear of the unit.
The power supply voltage is set by the factory for100-115V(nom. 110V) or 220-240V (nom. 230V) working.The setting is indicated by the indented metal strip on the fuse panel. Contact your dealer if the voltageneeds to be changed.
The mains indicator lamp on the keyboard is always lit when the unit is connected to the mains supply. The unitcan either be operated from the mains supply or from the built-in rechargeable battery.
Changing a Mains Fuse
If it is necessary to change a fuse, always replace with the correct rating i.e 2x200mAT for 230V, or2x315mAT for 110V .
To change a fuse press the two retaining lugs on side of the fuse panel (situated below the mains connector on theback panel. Remove the fuse panel and replace the fuse(s). Click back the fuse panel.
Intended Use
The CARDIOVIT AT-2 is a 6-channel ECG recorder with all (12) ECG signals simultaneously processed to provideinstant ECG recordings. Two automatic recording modes can be individually preset to enable one button ECGrecording of preferred print formats.

Introduction
The CARDIOVIT AT-2 is a 6-channel ECG recorder. All ECG signals are simultaneouslyprocessed to provide instant ECG recordings. Two automatic recording modes can beindividually preset to enable one button ECG recording of preferred print formats .
Individual lamps are provided to give power, paper error, filter, lead group and lead offindications.
In addition, any detected disturbance (i.e. loose electrode or end of paper), gives an audiblealarm and the corresponding indicator lamp flashes.
The AT-2 includes the following features:
• Low weight and compact dimensions
• Large A4 size printout from integrated quality thermal printer
• Built-in rechargeable battery for mains-independent use
• Simple one key operation
• Automatic or manual recording modes
• Selectable printing formats
• ECG memory for easy copying
• Interpretation program option (including measurements)

Location & Power
Location
Do not keep or operate the apparatus in a wet, moist, or dusty environment. Also, avoidexposure to direct sunlight or heat from other sources. Do not allow the unit to come intocontact with acidic vapours or liquids, as such contact may cause irreparable damage. Theunit should not be placed near X-ray or diathermy units, large transformers or motors.
The unit must be placed on a flat surface. The unit should not be operated in areas wherethere is any danger of explosion.
Power Supply
The unit can either be operated from the built-in rechargeable battery, or from the mains.
The mains connection is on the rear of the unit. The mains indicator lamp is always lit whenthe unit is connected to the mains supply.
A battery indicator lamp confirms battery operation. When the battery capacity is limited, theindicator flashes. To recharge the battery, connect the apparatus to the mains supply bymeans of the supplied power cable. A totally discharged battery needs less than 15 hoursto be fully recharged (60% in less than 3 hours, 90% in less than 7 hours).
A fully charged battery lasts approximately 6 hours of normal use. The unit can remainconnected to the mains supply without any danger of damage to either the battery or the unit.

Basic Information
Switching On and Off
The CARDIOVIT AT-2 is switched on by means of the green key and off by means
of the red key.
The unit is switched off after 5 minutes (30 seconds if battery capacity is limited) if no key ispressed and the patient cable is not connected.
Potential Equalisation
If the AT-2 is used in conjunction with other patient connected equipment, we recommend
that the potential equalisation stud ( ) on the rear of the unit is connected to the hospital/
building common ground with the yellow/green ground cable (Part-no. 2.310005).
When working from an emergency vehicle, the vehicle common ground can be used.
Basic Information
Switching On and Off
The CARDIOVIT AT-2 is switched on by means of the green key and off by means
of the red key.
The unit is switched off after 5 minutes (30 seconds if battery capacity is limited) if no key ispressed and the patient cable is not connected.
Potential Equalisation
If the AT-2 is used in conjunction with other patient connected equipment, we recommend
that the potential equalisation stud ( ) on the rear of the unit is connected to the hospital/
building common ground with the yellow/green ground cable (Part-no. 2.310005).
When working from an emergency vehicle, the vehicle common ground can be used.

Patient Cable Connections
The accessory kit of the electrocardiograph includes a 10-lead patient cable. This cable isplugged into the patient cable socket on the right-hand side of the unit and secured with thetwo screws.
The CARDIOVIT AT-2 is CF rated. The patient connection is fully isolated and defibrillationprotected. Protection against defibrillation voltage is however only ensured, if the originalSCHILLER patient cable (Part-no. 2.400070 / USA: 2.400071) is used. Make sure that duringECG recording neither the patient nor the conducting parts of the patient connection or theelectrodes (including the neutral electrode) come into contact with other persons orconducting objects (even if these are earthed).

Patient Cable Connections
The quality of the ECG is dependent on the preparation and the resistance between the skinand the electrode. To ensure a good quality ECG and minimise the skin/electrode resistance,remember the following points:
1. Ensure that the patient is warm and relaxed.
2. Shave electrode area before cleaning.
3. Thoroughly clean the area with alcohol.
4. Place the C4 electrode first - in the fifth intercostal space on midclavicular line.Then place:
• C1 in fourth intercostal space at the right sternal border
• C2 in fourth intercostal space at the left sternal border
• C3 between, and equidistant to, C4 and C2
• C6 on left midaxillary line on the same level as C4
• C5 between, and equidistant to, C4 and C6
Following these simple guidelines will ensure good results every time.

Recording an ECG in Automatic Mode
In automatic mode, a full 12-lead ECG is printed in one of two predefined formats with asensitivity of 10 mm/mV. These two formats are selected by the user to suit his specific needsand requirements (as detailed previously).
When the AUTOGAIN key is pressed before recording in automatic mode, the unit detects very
large waveform amplitudes and sets the sensitivity for the extremity and/or precordial leadsto 5 mm/mV to reduce the overlapping of traces.
To start the automatic ECG recording in Format 1, simply press AUTOSTART .
To start the automatic recording in the second format, pressALT
followed by
AUTOSTART .

Care & Maintenance
Care of your CARDIOVIT AT-2
The patient cable should not be exposed to excessive mechanical stress. Wheneverdisconnecting the leads, hold the plugs and not the cables. Align the leads in such a way asto prevent anyone stumbling over them or any damage caused by the wheels of instrumenttrolleys. The cable can be wiped with soapy water. Sterilization, if required, should be donewith gas only and not with steam. To disinfect, wipe the cable with any standard hospitaldisinfectant.
The casing of the CARDIOVIT AT-2 should be cleaned with a soft cloth on the surface only.
DISCONNECT THE UNIT BEFORE CLEANING.DO NOT, UNDER ANY CIRCUMSTANCES,IMMERSE THE APPARATUS INTO A CLEANING LIQUID OR STERILIZE WITH HOTWATER, STEAM, OR AIR.

12 Monthly Check
The unit should undergo a technical safety check every 12 months. This safety check shouldextend to include the following:
• Visual inspection of the unit and cables.
• Electrical safety tests according to IEC 601-1 and IEC 601-2-25.
• Functional tests according to the Service Handbook.
The test results must be documented.
Cleaning the Print Head
If the printer is used a lot, a residue of printers ink (from the grid on the printer paper) can buildup on the the print head. This can cause the print quality to deteriorate. We recommendtherefore that every month the print head is cleaned with alcohol as follows:
• Remove the paper tray. The printhead is found under, and in from, the paper trayrelease catch.
• With a tissue dampened with alcohol, gently rub the print head to remove the inkresidue. If the printhead is badly soiled, the colour of the grid ink will show on thetissue.

Replacing the Recording Paper
The recording paper must be replaced as soon as the end of the paper is indicated by a redstripe on the lower edge. After the indication first appears, there are about 8 pages left.However, we recommend that the paper be replaced immediately.
If no paper is left, the printing process is interrupted and the paper warning lamp starts toblink. After the paper has been replaced, the printout is restarted by pressing COPY or MANSTART or AUTO START.
A step-by-step description of how to change the paper is given on the next page.
